INSULATOR-PIN.

Specification of Letters Patent.

Patented March 1'7, 1908.

Application filed June 10, 1907. Serial No. 378,178.

T 0 all whom 'it /mllg/ concern:

Be it known that I, VILLIMI SCHARF- nAUsEN, residing at Payette, in the county ol' Canyon and State ol' .[daho, have invented certain new and use'lul Improvements in Insulator Pins, o'l' which the following is a specification.

My invention relates to certain new and useful improvements in insulator pins and it particularly seeks to provide an improved means of securing the pin into the cross arm as well as to provide an improved construction of pin which will be of maximum strength with minimum amount o'l materials used in its construction.

My invention also embodies certain novel details of construction, combination and arrangement of parts, all of which will be iirst described in detail, and then specifically pointed out in the appended claims, relierence being had to the accompanying drawings, in which:

Figure 1, is a perspective view ol the end of a cross arm with my improved invention applied. Fig. 2, is a side elevation of the insulator pin and cross arm, the cross arm being shown in section. Fig. 3, is a vertical longitudinal section of the inventiorL showing the position of the parts when the secur ing nail or spike is being driven in. Fig. 4, is a section on the line 4 l1 of Fig. 8, the parts being in the position in which the nail or spike has been driven home and the first clench or bend of the nail having been made. Fig. 5, is a horizontal section on the line 5-5 of Fig. 4. Fig. 6, is a sin'iilar View after the spike or nail has been clenched to its iinal position.

Referring now to the accompanying drawings, in which like numerals and letters ol reference indicate like parts in all of the. hgures, it will be seen that 1 designates the insulator pin which is provided with the cross arm engaging portion 1ZL and the insulator carrying portion lb, which is provided with a thread 1C to receive the insulator, or the thread 1c may be omitted, if desired.

1d designates a slot which extends to the upper edge of the body portion 1@L and at its lower end the slot 1b has a beveled portion le which merges with the outer tace of the body portion la.

At right angles to the slot le, the insulator carrying portion 1b of the pin is provided with a horizontal slot l" for a purpose which will be presently explained.

2 designates the cross arm in the apertures ol" which the body portion l:L olE the pin is adapted to be held and the manner in which the pin is held in the cross arm will G0 now be explained.

3 designates a nail or spike. of any approved type, such l'or instance as the wire nail type, which la'l'ter the nail has been placed in the cross arm aperture, is driven in through the slot l and as soon as the point 3 ot the nail or spike il engages the beveled portion l" ol' the slot it will be driven into the cross arm and a'lter the nail has been driven in the desired amount, the upper portion is bent overas at 3l at substantially right angles to the portion lying in the slot l, and is then again bent at substantially right angles to itself as at 3 to lie in the slot 1*'.

Thus it will be seen that my improved insulator pin and means for securing the same is of a very simple and el'l'ective construction and can bc easily and cheaply constructed, and the spike or nail 3 is locked in position to prevent any accidental withdrawal oi' the same, and `furthermore the lower end of the spike is driven at an acute angle to the axial line of the pin, and hence serves as a locking wedge to maintain the pin in the cross arm aperture.

From the lorcgoing description taken in connection with the accompanying drawings it is thought the complete construction, operation and many advantages of my invention will be readily understood by those skilled in thc art to which the invention appertains, and it may be 'further understood that any approved type of insulator 4 may be used in connection with the pin 1 since the particular construction of the insulator 4 forms no part of my present invention.

IVhat I claim is:

l. An insulator pin comprising a base portion and an insulator' carrying portion said base portion having a longitudinal slot, and said insulator carrying portion,having a transverse slot, said longitudinal slot at one end terminating adjacent said transverse slot, substantially as shown and described.

2. An insulator pin comprising a base portion and a reduced insulator carrying portion, said base portion having a longitudinal slot terminating at its lower end in an outwardly beveled portion, and said insulator carrying portion having a transverse slot held at substantially right angles to the longitudinal slot, all being arranged substantially as shown and described.

3. The combination with an insulator pin having a base portion and a cross arm having an aperture to receive such base portion, said insulator pin having an insulator carrying portion projecting upwardly from the base portion, said base portion having a longitudinal slot, of a locking member held in said longitudinal slot and projected into said cross arm, and means carried by the insulator Carrying portion of the pin for coperatively engaging with the locking member to lock the locking member -in place, substantially asvshown and described.

4. The combination with an insulator pin having a base portion and a cross arm having an a erture to receive such base portion, said insu ator pin having an insulator carrying portion projecting upwardly from the base portion7 said base portion having a longitudinal slot, of a locking member held in said longitudinal slot and projected into said cross arm, means carried by the insulator carrying portion of the pin for coperativel engaging With the locking member to loci the locking member in place7 said last named means consisting of a groove in the insulator carrying portion of the pin to receive an upset or bent-over portion of the locking means, substantially as shown and described.

5. An insulator pin comprising a base portion and an insulator carrying portion7 said base portion having a longitudinal slot in its outer wall, combined with a cross arm or support having an aperture to receive said base portion, a locking member held in said longitudinal slot and projected into the cross arm and having its upper end bent around said insulator carrying portion of the in to lie in a plane substantially at right ang es to that containing the longitudinal slot, substantially as shown and described.
